+Benchmarks Documentation:
+
+1. Run the bm_select_measure python file to get the benchmarks for individual measure.
+2. Enter the path for each dataset (Datasets can be downloaded from the website)
+3. Enter the measure to be benchmarked (Example: HammingDistance)
+4. Enter the size of the data set to be benchmarked (Example: 9000)
+
+Results:
+
+1. After it completes the benchmarking, results will be stored in a benchmarks directory
+   in an excel file.
